This plugin will display a notification each time a package with type"kdeconnect.telephony" is received. The type of notification will changedepending on the contents of the field "event" (string).Valid contents for "event" are: "ringing", "talking", "missedCall" and "sms".Note that "talking" is just ignored in this implementation, while the otherswill display a system notification.If the incoming package contains a "phoneNumber" string field, the notificationwill also display it. Note that "phoneNumber" can be a contact name insteadof an actual phone number.If the incoming package contains "isCancel" set to true, the package is ignored.
